OIL-SAVING DEVICE FOR OIL-WELLS.

Specification of Letters Patent.

Patented Nov. 2, 1915.

Application filed October 29, 1913. Serial No. 797,922.

To (7 whom it may concern Be it known that I. FRANCIS T. KERNS, a

citizen of the United States. residing at Beh-' ler, in the county of Monongalia and State of 'll'est Virginia, have invented certain new and useful Improvements in Oil-*tlVlIlg Desame.

This invention relates to improvements in oil saving devices and has for its primary 'object to provide a simple, practical and efiicient oil saver to be used when tubing is being drawn from a well.

Another object of the invention is to provide an oil saving device including a tubular body formed in two substantially semicylindrical sections, means for clamping said sections together around a joint in a line 1 of tubing, and means for conveying oil from within said body. I

Another and more important object of the invention is to provide in a device of this nature means for engagement with a pair of tongs whereby the device will be held in position as the tube sections are 'uncoiiled.

With these and other objects in view .as will become more apparent as the description proceeds, this invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fullydescribed and claimed. For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings. in wh1ch Figure 1 -is a side elevation of my improved oil saving device, showing the same in operative position. Fig. 2 is a side elevation. showing the device open. Fig. 3 is a horizontal section taken on the plane of line 3--3 of Fig. 1.. Fig. 4 is a fragmentary vertical section taken on the plane of line 4-4 of Fig. 1, Fig. 6 is a fragmentary sectional view showing how one of the packing strips is secured in position. and Fig. 6

is a horizontal sectional view taken on the plane of line 6 6 of. Fig. 1.

Referring in detail to the drawings by numerals, 5 designates as an entirety my improved oil saving device which .has a tubular body open at each end and formed of substantially semi-frusto-conical sections 6 and 7 which are hinged to each other as indicated by the numeral 8. The longitudinal edgesof the section 7 are grooved as indicated by the numeral 9 to receive the gaskets or packing strips 10. These strips extend the full length of the section, may be madeof any suitable material, such as leather or rubber. and are secured in position by means of any suitable fasteners 1,1. The longitudinal edges of the section 6 are formed with longitudinal grooves 12 into which the packing strips 10 are received when the sections are clamped together. Each section also carries adjacent its upper and lower edges the transverse gaskets or packing strips 13 which are received within grooves 14 and which extend between the packing strips 10 and grooves 12.

To clamp the sections together, I p'r'o- M videan eccentric .level or latch li which is connected by the links 16 to a projection 17 formed uponthe section 7 adjacent the free longitudinal edge thereof, and which is adapted to lockingly engage a similar projection 18 formed adjacent tlteefree longit idinal edge of the section 6. The projection 18 is formed with the concave face 19 which is engaged by the head 20 of the latch or lever.

Oil may be conveyed from the interior of the body to any suitable receptacle by means of a pipe or tube. not shown. connected in channels 23. These channels extend entirely through the sections. open upon the lower edges thereof, have their upper walls disposed in horizontal planes. and their Side walls converging downwardly and inwardly.

A jaw 24 slides within each of the channels or recesses 23 and has a shank which tip-- pears dovetailed in cross section or which conforms to the recesses. The outer endsof the shanks are extended downwardly and then inwardly to form the gripping portions 25 of the .jaw. Set Screws 26 thread down- Wardly through the upper portipns of the ofl'sets22'and engage the shanks of the jaws .30, the ja'ws 24 are engaged with the tongs, .as shown in Figs. 1 and 4, whereby the oil saver. is prevented from turning or otherwise to lock said jaws intheir adjusted positions.

In operation the device is clamped about a tubing section 27' anda collar or coupling 28,..Which operation may be conveniently performed by means of the hand projections 29 formed on the sections 6' and 7. The upper packing strips 13 engage the tubing 27, Q

coupling 28. .gether :With the packing strips form a -fse aled chamber about the tube and coupling.

and th'ellower packing strips engage the These packing strips to-' Before'unscrewing the tube 27 from the coupling 28, it Is customary to grasp the latter and hold it firmlyv against rotation by means of a pair of tongs 30. Haw lng gripped. the coupling with the tongs 'Q-moving from its proper position when the tube 27 is unscrewed. This locking feature is a veryv important featureof my invention, as i't-isi essential that some means be pro- -'v ide '1 for holding the oil saver against rotational and longitudinal movement.

' ,While I have shown and described the preferred embodiment of my invention,it will be understoodthat minor changes in con 'struction, combination and arrangement of partsmaybe made without departing from the scope and spirit of the invention claimed.

Having thus described my invention. I

claim I 1. In a device of the character described, a tubular body havmg a discharge opening formed therein, and adjustable means carried by said body adapted for engagement 40 with a stationary member whereby the body is held against rotational and longitudinal movement. I

2. In a device of the character described,

a body comprising a palr. of hinged semi- .frusto-comcal sections, means for locking said sections in their-closed positions, the lower edges of the sections being transversely recessed, and aws shdable within said recesses, the jaws being adapted/to en- -,qgage a stationary element to hold the body against movement.

3. In a device of the character described, a body comprising a pair of hinged semifrusto-conical sections, means for locking said sections in their; closed positions, the lower edges of the sections being transverselya-ecessed, jaws slidable within said recesses. and set screws for locking the. jaws in any adjustable position, the jaws being 'Oms O.
